To model this situation with a pair of linear equations, we use the information given:
-
Let \(b\) be the number of bags given away and \(c\) be the number of caps. They plan to give away a total of 2,000 items, which gives us the first equation: \[ b + c = 2000 \]
-
The cost of the bags is $10 each, and the cost of the caps is $5 each. They have a budget of $12,500 for these items, leading to the second equation: \[ 10b + 5c = 12500 \]
The correct pair of linear equations that model this situation is: \[ \begin{align*} b + c &= 2000 \ 10b + 5c &= 12500 \end{align*} \]
So the correct answer is: b + c = 2000; 10b + 5c = 12500
